<Page>1 POLONIA BANCORP REPORTS RESULTS FOR THE QUARTER ENDED MARCH 31, 2007 AND ANNOUNCES ANNUAL MEETING DATE Huntingdon Valley, Pennsylvania - May 3, 2007. Polonia Bancorp (the "Company") (OTCBB: PBCP), the holding company of Polonia Bank (the "Bank"), reported net income of $71,000, or $.02 earnings per common share, for the quarter ended March 31, 2007 versus a net loss of $167,000 for the quarter ended March 31, 2006. Higher net income for the quarter ended March 31, 2007 as compared to the quarter ended March 31, 2006 was primarily due to higher noninterest income as a result of lower losses on sales of investment securities and a recovery of a prior period chargeoff partially offset by higher noninterest expenses. Net interest income increased 3.8% to $1.18 million for the quarter ended March 31, 2007 from $1.13 million for the quarter ended March 31, 2006. Net interest income increased for the quarter due to a higher average weighted rate earned on investment securities and other interest earning assets and a higher average balance of loans and other interest earning assets, partially offset by higher interest expense paid on deposits. The increase in the higher average weighted rate paid on deposits was primarily attributable to our new tiered signature money market account. The Bank recorded a recovery for loan losses of $225,000 as a result of recoveries of $257,000 during the March 31, 2007 period. There was no provision for loan losses recorded during the March 31, 2006 period. At March 31, 2007, nonperforming loans totaled $226,000, or 0.19% of total loans, compared to $267,000, or 0.28% of total loans, at March 31, 2006. Noninterest income was $174,000 for the quarter ended March 31, 2007 compared to $75,000 for the quarter ended March 31, 2006. The increase in noninterest income was primarily due to the lack of losses on the sale of investment securities during the 2007 quarter as compared to the prior year period, partially offset by lower reported income attributable to bank-owned life insurance, lower deposit-related fees and charges and the absence of gains on foreclosed real estate sales which occurred in the 2006 quarter. Noninterest expenses were $1.5 million for the quarter ended March 31, 2007 compared to $1.4 million for the quarter ended March 31, 2006. For the 2007 quarter, the increase of $100,000 primarily reflected higher costs associated with compensation and employee benefits and professional fees related to operating as a public company. Total assets declined $7.8 million, or 3.8%, to $195.6 million at March 31, 2007 from $203.4 million at December 31, 2006. Contributing to the decrease in assets were decreases of $13.0 million in cash and cash equivalents related to the refund of $12.2 million in non-eligible stock subscriptions and a $1.2 million decrease in investment securities primarily due to the repayment of available-for-sale mortgage backed securities, partially offset by a $6.1 million increase in loans. <Page>2 Total liabilities were $171.1 million at March 31, 2007 compared to $191.6 million at December 31, 2006, a decline of $20.5 million or 10.7%. The decline in liabilities was mainly due to a temporary increase in liabilities at December 31, 2006 from $24.8 million of stock subscription funds. With the closing of the Company's stock offering on January 11, 2007, liabilities decreased primarily as a result of the refund of $12.2 million in non-eligible stock subscriptions and the transfer of $12.6 million in proceeds related to the Company's stock offering to stockholder's equity, partially offset by a $4.2 million increase in deposits. Total stockholders' equity increased $12.7 million to $24.5 million at March 31, 2007 from $11.8 million at December 31, 2006. The increase in equity was primarily related to the receipt of $12.6 million in net proceeds related to the Company's stock offering.
